Abstract

The generator has a working chamber (9) containing a piston (1), two displacers (2,3) and a fluid such as helium. The displacers are linked by a rod which passes through the piston and directed by control windings (5). Heat is applied (10) to the extremities of the working chamber which is cooled centrally by radiators (7). The piston constitutes the generator rotor and electrical power is generated in stator windings (6) Independent claims are made for methods used to generate electricity
